I have the chance to buy a used Cartoni Action Pro tripod and head for about $250. What are your opinions on this tripod and head? My rig is really light. Is there a minimum for the load range? It looks like a heavy tripod. I would have rather a lightweight one particularly a carbon fiber one. However, they are considerably more expensive. If the Caroniti fluid head is of good quality, this seems a good price. What do you think?
